I took my Mercedes SLK into the dealership to have one of the wheel barrings and rotors replaced. First they said they would have to replace the whole assembly because the couldn't remove a cap. They over charged the parts buying them directly from the Mercedes dealership at full cost when we agreed to order the aftermarket part, i.e. bad internal communication in the service department.
Later they added that I would need a new ABS sensor, which oddly was working fine before they started. They also want to charge me over $100 for the sensor when it is $40 online.
Additionally, I waited 5 hours for my car to be fixed. I personally could have done this in my driveway in an hour, which I now regret. As it is slightly more complex than changing a tire.
Just overall bad management, bad internal communication, and definitely NOT the Toyota Way.
